Collision Avoidance and Parking Assist Systems: Service Precautions

General Instructions/Safety Instructions

The following points must be observed during vehicle diagnosis:
- The Park Assistant signals readiness with a short signal tone, provided that the ignition is switched on and the reverse gear is engaged
- After the battery is connected, volatile memories must be reprogrammed. In the case of radio coding and tuning, the customer must be informed of decoding and the deleted tuner memory.
- After troubleshooting or repairs, erase the fault memory with the Porsche System Tester 2 and carry out a test drive.
- After the test drive, read out the fault memory with Porsche System Tester 2 again.


CAUTION.
Danger of damage due to improper handling of the battery and the control module connectors.
- Never disconnect battery with engine running.
- Never start engine without securely connected battery.
- Never pull off or push on plug connections of the control modules or other electronic components when the ignition is switched on.


WARNING.
Danger of injury and damage to vehicle when the vehicle is rolling backwards.
- Reverse gear must be engaged and the ignition must be switched on; otherwise the Park Assistant System is deactivated.


WARNING.
Danger of injury and damage to vehicle when the system limits are reached. The system does not tree the driver from his/her responsibility to be careful.
- Short obstacles such as a person lying down cannot be detected.
- The reflecting behaviour of the system can be impaired by sound-absorbent obstacles such as powder snow or sound-reflecting obstacles such as glass surfaces.
- Very thin obstacles and obstacles with no reflecting surfaces cannot be detected.
